Related application

The application requires to enjoy the rights and interests of No. the 2007242910th, the Australian patent application of No. the 564282nd, new zealand patent application submitting on December 13rd, 2007 and submission on December 13rd, 2007, and these two patent applications are incorporated this paper with way of reference into its integral body.

Technical field

The present invention relates to comprise the high concentrate formulation of glyphosate of the triethanolamine salt of glyphosate, and particularly, relate to the preparation of the combination that comprises these salt and sylvite, with and using method.

Background technology

Glyphosate is known, effective weed killer herbicide.Have good several organic ammonium salts that are used as the glyphosate of weed killer herbicide, it comprises methylamine salt and dimethylamine salt, and gives an example, monoalkyl ammonium and dialkyl ammonium (referring to, as US 4,405,531).At present, multiple glyphosate formulation is sold on market, and many in them are the aqueous solution, and these aqueous solution can be used as it is or be diluted before use.

Usually the form with salt provides glyphosate, and these salt present sufficiently high solvability so that the herbicidal formulations of high concentration to be provided in water.For example, the preparation of known high concentration be potassium (K) salt of isopropyl amine salt (IPA), MEA (MEA) salt and multiple glyphosate preparation (referring to, as US 6,277,788; US 6,365, and 551; WO 01/89302).

Based on the reason of various economy and environment, the preparation of expectation high concentration.For example, expectation provides the amount of preparation to reduce transportation and cost of disposal and to reduce the packaging material that must be dropped of high concentration.The preparation of high concentration is stable in storage and transportation preferably and keeps usefulness.And the preparation of high concentration is provided as clarifying best, uniform liquid, this liquid are stable under at least up to 50 ℃ temperature and are being low to moderate under 0 ℃ the temperature and can present any precipitation.

Yet the preparation of high concentration can cause high viscosity.For example, the preparation of the IPA salt of normally used glyphosate is in the concentration greater than 350 gram acid equivalents every liter (gae/L), and especially viscosity becomes big greater than the concentration of 440gae/L the time.High viscosity makes preparation be difficult to measure and pumping, and is especially true during the lower temperature that runs into when the season of growth begins usually.

Available glyphosate formulation generally includes surfactant.Resulting preparation comprises that surfactant can expect, because can present the activity of weeding of enhancing or the feature of other improvement.For example, known glyphosate formulation comprise with the alkyl betaine surfactant of other combinations-of surfactants (referring to, as WO 03/067689).

The MEA salt of glyphosate and the major limitation of K salt are incompatible with the kinds of surface activating agent.Particularly, when the overall mean of carbon atom adds that the summation of the mean of oxyethylene group is equal to or less than 25, polyoxyethylene alkyl amine only compatible with the MEA salt of glyphosate (referring to, as, US 6,277,788).Similarly, many surfactants commonly used are not compatible with glyphosate K salting liquid.For example, when ethoxylation degree is no more than approximately 5 the time, the alkylamine ethoxylate surfactant is unique compatible (that is, allowing uniform mixture), and this surfactant has the bigger possibility that causes eye irritation.

In addition, some surfactant can interact to increase the viscosity of herbicidal formulations with glyphosate salt.For example, when making up with glyphosate salt, some surfactants in the compound of oxyalkylene alkyl amine have increased the viscosity of preparation.If viscosity is too high, may be difficult to dispose concentrated weed killer herbicide.And full-bodied liquid is difficult to measure exactly, so that be applied to plant or be diluted to the spray solution of low concentration.Depend on concentration and specific surfactant, herbicidal formulations can form gel, is not to carry out even this makes great majority use, also extremely difficult carrying out.

In view of the above problems, exist association area is carried out other improved lasting demand, comprise presenting low viscosity and suitable effective improved high concentration herbicidal formulations.The invention solves these demands and multiple benefit and advantage are provided.
